Frequently Asked Questions
-
What does a dekapascal measure?
-
A dekapascal (daPa) is an SI-derived unit measuring pressure, representing force per unit area equal to 10 pascals.
-
Why convert from dekapascal to centimeter mercury (0°C)?
-
Converting allows interpreting pressure measurements in manometric units commonly used in laboratories and engineering where mercury columns are standard.
-
Does this conversion work for all temperatures?
-
No, this conversion is specific to mercury at 0°C under standard gravity, so deviations in temperature may affect accuracy.
Key Terminology
-
Dekapascal [daPa]
-
An SI-derived pressure unit equivalent to 10 pascals, used to quantify mechanical stress or pressure.
-
Centimeter mercury (0°C)
-
A pressure unit representing the pressure exerted by a 1 cm column of mercury at 0°C under standard gravity.
-
Conversion Rate
